Purpose: The purpose of this study was to compare the short-term changes in retina and choroidal tissue after femtosecond laser-assisted cataract surgery (FLACS) and standard phacoemulsification (PE) surgery.
Methods: In all, 25 eyes undergoing FLACS and 27 eyes undergoing PE surgery were included in this nonrandomized, retrospective, cross-sectional study. Central retinal thickness (CRT) and choroidal thickness (CT) were measured pre- and postoperatively (at day 1, 1 week later, and after 1 month) with spectral domain optical coherence tomography (OCT) in all patients and were compared. For group comparisons, chi-square test and independent t-test were used. Postoperative values were compared to the baseline using a paired t-test. The magnitude of the change from baseline to the peak was analyzed by multiple regression models in an attempt to explain possible influence variables.
Results: Pre and postoperative CRT measurements were similar in both groups. The mean subfoveal CT at day 1, after 1 week, and 1 month were significantly higher than baseline CT measurements in the PE group.
Conclusion: FLACS might have an advantage in regard to postoperative choroidal changes.
